ATTACHMENT FOR CAKE-FORMERS.

Specification of Letters latent.

Patented May in, 1921.

Application filed July 22, 1920. Serial No. 398,288.

To all whom it may concern:

Be it known that I, ALFRED C. HAMMOND, a citizen of the United States, residing at Columbia, in the county of Ri'chland and State of South Carolina, have invented certain new and useful Improvements in Attachments for Cake-Formers, of which the following is a specification.

This invention relates to improvements in machines for forming cotton seed meal into cakes and the invention has for its principal object to provide means to maintain the press cloth in proper position during the forming operation to insure uniformity in the size and shape of the cakes formed with the consequent increase in the yield of oil therefrom.

A further object is the provision of a cloth retaining and guiding means for cake formers which is entirely automatic in its operation being actuated by moving parts of the machine so as to avoid interference with'the convenientremoval of the formed cakes from the forming box.

A further object is the provision of an attachment of, this character which is of such simple construction as to require only very slight modification of conventional types of cake formers now in use to adapt them for use in connection with the attachment.

With these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims and in the drawings illustrative of the preferred embodiment of the invention.

In the accompanying drawing:

Figure 1 represents a fragmental front elevation of a cake former illustrating the attachment applied thereto.

Fig. 2 represents a fragmentary transverse sectional view on the line 2-2 of Fig. 1.

' Fig. 3 represents a similar view on th line 3-3 of Fig. 1, and,

Fig. 4; represents a plan view of the attachment removed from the forming machine, the pin projecting cam and pin retracting fingers being shown. 1

Referring to the drawing in detail reference will first be had to the parts of a conventional type of cake former which have been illustrated in order to disclose the mode of application of the attachment thereto and its operation. In the drawmg, the numeral 5 indicates a base plate supporting a pedestal stand 6 on which is arranged the vertically movable cake forming box T, the vertical movement of which, under pressure, with relation to the swinging head block 8 is utilized to preliminarily compress the cake into proper form. The swinging head block 8 is pivotally mounted at 9 by bracket 10 carried by a relatively stationary part of the stand or support 6 and in the type of forming'box illustrated in the accompanying drawing the open ends thereof are closed during the forming opera tion by the automatically actuated end gates 11. The swinging head block is locked in closed position against accidental displace ment by a pivoted latch 12 engageable with a keeper plate 13 also carried by a relatively stationary part of the stand or supportfi.

A fluid pressure actuated charging box 14 is mounted for reciprocationupon a supporting table 15 and is adapted to be projected over one end of the forming box 7 for depositing a predetermined quantity of cotton seed meal therein.

With the exception of fastening adequate supportingbrackets for the attachment to the conventional type of cake former the only modification thereof necessary to adapt the attachment thereto resides in the formation of four apertures 16 two of which are formed in one side wall 17 of the box and the other two in the other side wall of the forming box the several openings being arranged adjacent the automatically actuated end gates 11. Pairs of horizontally movable cloth retaining pins 18 are movably mounted in the openings 16, and, as shown in Figs. 2 and 3 are arranged relatively close to the bottom of theforming box The pins at the front of the forming box are connected with the crank ends 19 of a horizontal shaft 20, the latter being supported in brackets 21 adequately secured to the front part of the forming box. As. a

.matter of economy, the extremities of the formlng box,

Simultaneous and corresponding move ment of the two pairs of pins 18 effected through a connecting rod 23 the extremities taneous withdrawal of both pairs of pins incident to the automatic actuation of one of'the shafts. V

A cam plate 26 is rigidly connected with the charging box it and is arranged so as to engage the cam face 27 thereof with the adjacent crank end 22 of the shaft 21 during the forward projection of the charging box 14, prior to the discharge of material into the forming box 7. ,The pressure exerted bythe cam plate against the arm of the shaft 21 causes-the latter to revolve and project the pins 18 through the rear side wall of the the movement of the shaft 21 being transmitted to the shaft 20 through the connecting rod 23 to simultaneously effect the inward projection of the front pins 18.

'- Retraction of the several pins from the forming box subsequent to the formation of a cake is effected by a spring latch member 28 carried by the head block 8 and provided with a lateral shoulder 29 engageable with a crank 30 formed on the adjacent portion of the shaft 20. The crank 30 is directed rearwardlyso as to cooperate with the shoulder of the finger 28during opening movement of the swinging head block 8 and thereby rotate the shafts 20 and 21 in the direction to effect retraction of thepins.

Assuming that the swinging head block 8 has been actuated to withdraw the several pins 18 from the forming box, the press cloth is positioned upon the bottom of the forming box and the charging box 1 1 is actuated to project forwardly and deposit a predetermined quantity of material in the forming boX. During the forward movement of the chargingbox, the cam 26 carried thereby engages the adjacent arm of the shaft 21 and projects the several pins 18 into the forming box above the cloth 31. During return of the charging box to its initial position the several pins 18 remain in the forming box and the cloth is subsequently folded over the cake, the pins '18 serving as retaining means to insure folding of the cloth at a predetermined point. The swinging head block is subsequently closed and locked and the forming box is actuated to slightly compress and form the cake, the end gates 11 closing the ends of the forming box. During the closing movement of the swinging head block, the beveled face of the shoulder 21 causes outward deflection of the spring finger 28, the latter subsequently springing inwardly to engage the working face of the shoulder with the pin of the crank 30. As

scribed comprising a the swinging head block is subsequently moved upwardly and the end gates 11 opened, the shoulder 29 actuates the crank shaft 20 to effect the retraction of the pins 18 carried thereby, the retraction of the other pair of pins 18 being effected through the connecting rod 23 and shaft 21, thus permitting of the convenient withdrawal of the formed cake from the forming box.

From the foregoing, it isevident that by the use of the attachment a cloth is reliably retained in proper position during the forming operation thus insuring uniformity in the shape and is furthermore evident that the attachment is entirely automatic in its operation requiring no attention whatever upon the part of the attendant of the machine;

What I claim is:

1. An attachment for cake formers including opposed movable pins arranged in a cake former body for maintainingthepress cloth in position during the folding thereof. 1
